Body Facts: Immune System
- The skin secretes antibacterial substances that hinder the penetration of bacteria and fungi through the skin. That’s why we don't wake up in the morning with a layer of mold growing on our skin - most bacteria and spores that land on the skin die quickly.
- Tears, sweat and mucus contain an enzyme (lysozyme) that breaks down the cell wall of many bacteria.
- Lymph nodes contain filtering tissue and a large number of lymph cells. When fighting certain bacterial infections, the lymph nodes swell substantially, due to the bacteria and the cells fighting them that you can actually feel them. Swollen lymph nodes may be a good indication of an infection.
